Can you explain voltage sources in series and parallel completely?

If I were you, I would start on this subject by following the basic rules and definitions and see where they lead you in a practical situation. A practical situation will always always always involve a finite (internal) resistance in series with any 'voltage source' and, when two such sources are connected in parallel, there is the likelihood of large currents flowing through these series resistances. (Different nominal emfs). Nothing magic or paradoxical here - just real life.
The notion of connecting idea voltage sources in parallel (and also connecting ideal current sources in series) is actually nonsense and hasn't any relevance to EE. Likewise, no one considers massless objects in mechanics problems or infinitely long, rigid rods and expects to get any sense out of the result.
